The Marmot Men's Fusion Fleece Jacket has what you always hoped your dream fleece would have: wind-resistant, DWR-coated nylon material throughout the chest, shoulders, and arms for protection with a blend of nylon and elastane at the sides, back, and underarms for uninhibited movement and extensive breathability. Now you can run head-on into a spring shower and not feel like a steamed oyster in a restrictive shell.

Nice versatile jacket

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 6'0"
    Weight: 175 lbs

I like to wear this jacket wile running on cold days. The thumb holes are a nice feature. It is slim fitting so it also works very well as a mid-layer.


Action Hero

  • Gender:Male

Although I would say this thing fits true to size, the fit is super slim like an action hero costume so don't expect to wear multiple layers underneath. The web image color matches (Slate Grey/Steel). Elastane fabric definitely allows you to move freely so the description is accurate with this feature. I've used it on some mid-length mt bike rides and full day ski-a-thons without feeling like a wrestler trying to make weight

Not a lightweight!

    At temps in the mid-50s and below this jacket is comfy, but it is too much for warmer days. I have not worn it in the rain, and don't think I'd want to in anything more than a sprinkle. It does not appear to be designed to withstand much water. I had hoped it would be good for summer rain, but it was the wrong choice. It's a nice jacket for running and biking under the right conditions.
